Hello good people.
I obtained a number of powders from a friend that passed away last year. One is a nearly full 20 Lb keg (!) with a home made label that simply reads 4831 and dated 5/5/73. Visually, the powder is similar to a modern sample of IMR 4831 and different than H4831 I have around. Lately I have heard about "Surplus 4831" and several versions of H4831. Is there a way to tell what I have? Should I just work up loads using data for IMR4831 and not think about it too much? None of my manuals list data for "Surplus 4831".
All the 4831's seem to be popular with reloading folks and the powder is in good shape so I'd like to try it. I'm loading for my L61R 30-06 and a Wby Vanguard .300 Wby Mag.
